transformation products of tire rubber antioxidant 6ppd in,6ppd, a tire rubber antioxidant, poses substantial ecological risks because it can form a highly toxic quinone transformation product (tp), 6ppd-quinone (6ppdq), during exposure to gas-phase ozone. important data gaps exist regarding the structures, reaction mechanisms, and environmental occurrence of tps from 6ppd ozonation. to address these data gaps, gas-phase ozonation of 6ppd was.
antioxidants are prevalently used during rubber production to improve rubber performance, delay aging, and extend service life. however, recent studies have revealed that their transformation products (tps) could adversely affect environmental organisms and even lead to environmental events, which led to great public concern about environmental occurrence and potential impacts of rubber.

environmental fate of tire-rubber related pollutants 6ppd and,to enhance tire durability, the antioxidant n- (1,3-dimethylbutyl)-n′-phenyl-p-phenylenediamine (6ppd) is used in rubber, but it converts into the toxic 6ppd quinone (6ppd-q) when exposed to oxidants like ozone (o 3), causing ecological concerns. this review synthesizes the existing data to assess the transformation, bioavailability, and.
6ppd rubber antioxidant: characteristics, applications
6ppd (6ppd or n-(1,3-dimethylbutyl)-n'-phenyl-p-phenylenediamine) is a widely used rubber antioxidant that plays a vital role in the production of rubber products. this article aims to provide an overview of 6ppd, its characteristics, its applications in rubber product manufacturing, potential product combinations, and important considerations for commercial procurement. 1. what is 6ppd? 6ppd.
sunlight-induced transformation of tire rubber antioxidant n,the huge consumption of the tire rubber antioxidant n-(1,3-dimethylbutyl)-n′-phenyl-p-phenylenediamine (6ppd) has resulted in pervasive contamination in aquatic environments. more importantly, the transformation product of 6ppd, i.e., 6ppd-quinone (6ppd-q), is raising increasing concerns due to its high toxicity to aquatic organisms. however, whether and how 6ppd-q can be formed from 6ppd in.
- What is the content of 6PPD in rubber?
- Typically, the content of 6-PPD in rubber materials ranges from 0.4% to 2% . During its production and use, 6-PPD can be transported to exposed surfaces and enter the environment. These antioxidants are highly reactive to ozone . 6-PPDQ is more stable than 6-PPD.
- What causes 6ppd-q in soil and tire rubber wear particles (TRWPS)?
- There is a linkage between 6PPD-Q in soil and tire rubber wear particles (TRWPs), indicating its origin from sources associated with vehicular activities (Klockner et al., 2019). Approximately 50% of TRWPs can infiltrate the soil, releasing bound chemicals like 6PPD (Klockner et al., 2019).
- Can 6PPD be removed from end-of-life tires?
- We introduce a decontamination strategy that removes 6PPD from end-of-life tires before it enters the broader ecosystem. We demonstrate the catalytic upgrade of 6PPD to safe chemicals and the valorization of crumb rubber to aromatics and carbon black using microwave-assisted pyrolysis.

- Which phosphorus flame retardant produces the highest amount of rubber antioxidants?
- The production and consumption of rubber antioxidants have been increasing globally in recent years and are much higher than the consumption of phosphorus flame retardants . 6-PPD produces the highest amount of rubber antioxidants compared to other antioxidants .
